According to press materials, the play probes "the mind of the greatest detective of all time." Following a seemingly deadly encounter with his nemesis, arch criminal Professor Moriarty, at Reichenbach Falls, secrets and betrayal are slowly revealed. Watson finds his loyalty and friendship tested to the very limit. Holmes is forced to turn his unswerving powers of deduction upon himself, and the true relationship between Holmes and Moriarty is finally revealed.

The play was first performed in the West End in 1988 by Jeremy Brett and Edward Hardwick, reprising their roles as Holmes and Watson from the popular TV series "The Adventures of Sherlock Holmes," adapted from the Conan Doyle books by Jeremy Paul. The play is an original work by Paul, who believes he has the blessing of Conan Doyle himself for writing the play: "When the American actor William Gillette wrote the first stage play about Holmes, he sent a telegram to Sir Arthur Conan Doyle, asking: 'May I marry Holmes?' Conan Doyle wired back: 'Marry him or murder him or do what you like with him'... Many of the words you will hear are Conan Doyle’s own, taken on and fashioned into an original mystery which I hope will intrigue Conan Doyle himself if he’s looking in."

Egan's extensive stage credits include Hamlet, Richard II, Journey’s End, Art and Noises Off. In 1991 he directed and co-starred as Astrov with Richard Briers in Uncle Vanya.

Daws is best known for his TV roles in "The Royal," "Roger Roger," "Outside Edge" and "Jeeves & Wooster." His most recent West End theatre appearances include Public Property at the Trafalgar Studios and Caught in the Net at the Vaudeville.

The play is directed by Robin Herford (whose credits include the long-running Woman in Black), with design by Simon Higlett, lighting by Matthew Eagland and sound by Matthew Bugg, who has also written the original music. It is presented by Ian Fricker and Richard Temple. To book tickets, contact the box office on 0844 412 4659, or visit www.nimaxtheatres.com.
